Because Mina Hakuba sounds absolutely different from Mina Harker in a thick Japanese accent. No possible connection there at all mate. Why would you possibly believe something so readily debunk-- oh wait.
I don't understand what the implication is here, because I thought my post was clear.
The events of the movie are not exactly the same as the events of the novel.
- Are Mina Harker/ Hakuba connected by one referencing the other's name? Yes
- Does the "Elisabetha was reincarnated into Mina Harker" twist from the film have its place in CV? No, the events of the book and film aren't exclusive.*
*One of the reasons I state that the film is not canon is due to the way Vlad Tepes is presented. His wife Elisabetha is obviously not the same woman from LOI. The film's backstory also obviously differs from the CV universe being that this particular backstory given its context should actually be referencing Lisa in the CV universe, not Elisabetha. In addition, the start of the film shows Vlad stabbing the cross which starts to bleed, and offers an explanation about how he became "unholy" or anti-Christ so to speak, which directly conflicts with LOI's backstory. However, none of this is mentioned in the original novel, which doesn't conflict with the Castlevania's canon either).
- The book is explicit about Quincy's death and how/ why he died killing Dracula. While I don't recall the ending to the film my memory tells me it was different to the novel.
I know your stance on this BA, I don't believe Elisabetha (from LOI) was reincarnated into Mina Harker or subsequently into Mina Hakuba.
